SacredFire NF-555 HELP

[koolranch]

I got this light form DX, the scu is 30682 What i would like to know is can I mod this to be a one mode light? It has no memory and I do not like the fact that after you use it it will restart on the next mode. Thanks for any help.

measure the driver boards diameter then search DX and KD for simlar ONE_MODE drivers...if it is 17mm, DX 3256 is HIGHLY recommended
